like that pack u get void and elf pack i thingk it is like this
eg.void pack is worth 1mil tc and elf is 500tc thats 1.5mil tc it cud of cost like
1$=5k tc
so $100=500k
and 300$= 1.5mil
so the shop cud of make the pack 350$ so it will have the same valu of the tc they will get if they sell it then i dont thingk they will buy it and sell it and make good profit they just can buy tc then
